On the other hand, if levels are too high, it can lead to an overstocking of products and wasted resources.

When a website ranks higher in the search results, it's more likely to be seen by users. This can lead to increased organic traffic and visibility. That’s why businesses should pay attention to their keyword rank and strive to improve them.
